What is the definition of "opensm won't work at all ?" I am presuming
that somehow the ports are not brought to active. Is that it or
something else ?

Can you provide the salient part of the logs ? How was OpenSM invoked ?
Was it with -V ?

The difference is that ibnetdiscover only performs gets whereas OpenSM
does both gets and sets.
